GREENHOUSE AND CONSERVATORY.
Keep the conservatory as cool by day as is consistent with the health of
the plants. By such means they will remain longer in bloom, and will be
more enjoyable for parties inspecting them.
Camellias.--Continue to encourage the growth of those
that have done flowering by increasing the temperature, by frequent syringings, and by a liberal supply of water at the roots. If any have made their growth, and have formed their blossom-buds, they will require more light and less moisture for the future. Cinerarias.--To continue them in a healthy blooming state it is necessary to attend to them carefully, that they may not droop for want of water, nor be saturated with it. When the sun is powerful, slight shading is necessary for a few hours in the middle of the day, to prevent the blooms from losing their brilliancy; and plenty of air to be given when the weather is mild. Fuchsias.--Having been treated with plenty of heat and moisture, they will now be making rapid growth, and will be fit to shift into their blooming-pots, using a light, rich soil for the purpose. New Holland Plants.--Top and syringe frequently all such plants as are growing freely. Stake and tie them as they may require. Pelargoniums.--Continue to stake and tie the shoots that require it in due time. Some clear liquid manure (cowdung water, for instance) may be given to plants that are well established with roots and showing their trusses of bloom; and sufficient space to be given for each plant to develope its natural beauty. We would advise shading only when there is a fear of scorching from the usual sudden sunbursts of April weather. Ply the syringe every fine evening to refresh the plants, and to keep down insects, until the flowers expand, when syringing should be discontinued. STOVE AND ORCHID-HOUSE. The stove plants recently potted will now be making fresh growth. Allow no diminution of bottom heat, and keep up a warm, moist atmosphere. Give air when the thermometer indicates 90 deg.. Continue to shift Gesneras, Clerodendrons, and other such free-growing plants, as they require it. The Brassias, Cattleyas, some of the Dendrobiums, Gongoras, Peristerias, Phaiuses, Sobralias, Zygopetalums, and other such Orchids, will now be growing freely, and will therefore require a considerable amount of atmospheric moisture. If the roof is covered with climbers, a little management in trimming them will obviate the necessity of outside shading, and will give an additional feature of interest to the house. The plants on blocks, or suspended in baskets, will require very frequent syringings to keep them in a healthy-growing state. Plants in bloom may be removed to the conservatory, or any other house with a drier atmosphere, to prolong their period of blooming. FORCING-HOUSE. Cherries.--When they begin to change they will require free exposure to light, and abundance of air, to bring out their colour; and, at the same time, a diminution in the supply of water. Carefully examine all curled leaves, and destroy the grubs they contain. If the trees are very luxuriant, and are making strong foreright shoots, stop them to within a few buds of the main branch. Figs.--Give the trees in pots some clear liquid manure when they are swelling off. Stop the shoots at about six or eight inches, and thin out any useless shoots. Syringe and water freely. Melons.--Keep the vines thin, and stop regularly. Shade only in very hot weather. Water sparingly overhead. Plant out succession crops. Peaches and Nectarines.--When the fruit in the early house has gone through the critical process of stoning, the final thinning should take place; the borders--if inside, or out, or both--should be copiously supplied with water; using liquid manure whenever a weak habit, from poor soil or over-exhaustion, shows it to be necessary. Syringings to be given twice a-day--early in the morning and at shutting-up time. The night temperature to be no more than 50 deg.; but during the day it may range to 85 deg., if accompanied with air in liberal quantities. Pine Apples.--Lessen the moisture amongst the fruiting plants when they approach maturity. Shift and grow on the young stock in a moist atmosphere; admit air freely in fine weather; prepare beds, and turn out the plants, if preferred. Strawberries.--They should be kept near the glass: temperature, 65 deg. to 70 deg. by day, and 55 deg. to 60 deg. by night; succession crops rather cooler. Reduce the water to those ripening. Support the stems, and thin the fruit where superior produce is wanted. Keep them clear of runners and decayed leaves, and give an abundance of air. Vines.--Continue to thin the Grapes in the early houses: a few berries may require to be taken out of some of the bunches up to the time of their changing colour. Keep up a high temperature--about 75 deg. by day and 60 deg. by night: in later houses, where the bunches are in course of formation, it is a great object to bring them out well. In later houses, where the bunches are formed, or in bloom, let the heat be moderately increased, and admit an abundance of air at all favourable opportunities. Shift pot Vines often, and keep them near the light.
